45% of all expenditure in German industry is on materials, with costs for personnel costs not even reaching 20%. Businesses are paying out approximately 500 billion euros per year for steel, plastic and intermediate products. More efficient production processes and more modern technical plants could reduce these costs by a fifth, according to a study carried out by Arthur D. Little in cooperation with the Wuppertal  Insitute for Climate, Environment and Energy and the Fraunhofer Gesellschaft.
